State-of-the-art surgery for sigmoid diverticulitis

Abstract

Summary Background In the last two decades, there has been a Copernican revolution in the decision-making for the treatment of Diverticular Disease. Purpose This article provides a report on the state-of-the-art of surgery for sigmoid diverticulitis. Conclusion Acute diverticulitis is the most common reason for colonic resection after cancer; in the last decade, the indication for surgical resection has become more and more infrequent also in emergency. Currently, emergency surgery is seldom indicated, mostly for severe abdominal infective complications. Nowadays, uncomplicated diverticulitis is the most frequent presentation of diverticular disease and it is usually approached with a conservative medical treatment. Non-Operative Management may be considered also for complicated diverticulitis with abdominal abscess. At present, there is consensus among experts that the hemodynamic response to the initial fluid resuscitation should guide the emergency surgical approach to patients with severe sepsis or septic shock. In hemodynamically stable patients, a laparoscopic approach is the first choice, and surgeons with advanced laparoscopic skills report advantages in terms of lower postoperative complication rates. At the moment, the so-called Hartmann’s procedure is only indicated in severe generalized peritonitis with metabolic derangement or in severely ill patients. Some authors suggested laparoscopic peritoneal lavage as a bridge to surgery or also as a definitive treatment without colonic resection in selected patients. In case of hemodynamic instability not responding to fluid resuscitation, an initial damage control surgery seems to be more attractive than a Hartmann’s procedure, and it is associated with a high rate of primary anastomosis.
